AUTOMATIC DISPLAY-RACK.

The invention has as its primary object accordingly, to provide a device of this character which will, when set in operation, successively display a plurality of cards or other articles, and so constructed that the said cards will be automatically shifted as they are successively brought into position for display, so that each of said cards at the proper time, will reverse its position to consequently bring its oppositeside into position for display and to, at the same time, uncover the next succeeding card for display.

The invention has as a further object to provide an improved construction wherein each of the cards or articles being dlsplayed upon initially arriving at the position for display, will be automatically restrained for maintaining the card or article stationary for a suitable length of time, and wherein 7 each of said cards or articles, upon being thus restrained, will automatically restrain the next succeeding card for properly bringing it into position where it will be automatieally restrained uponthe release of the card immediately in advance thereof;

A further object of the invention is to provide a device of this character so constructed as to automatically and successively display opposite sides of each of the cards or articles carried thereby, and wherein each of said cards will, by gravity, be automatically moved to effect this result.

Another obiect of the invention in this connection, is to provide automatic means for successively moving each of the cards or Specification of Letters Patent.

articles as they advance into position for display, against the action of gravity, to substantially the highest point of their movement against their tendency to gravitate, to such position that upon theautomatic release of each of said cards or articles, they will normally gravitate to effect the reversal thereof;

A still further object of the invention is to provide in an improved device of this character wherein a plurality of cards or articles are being displayed and moved into position for display at a certain rate of speed, an independent card or device moving at a greater rate of speed and so constructed as to normally attract attention.

And the invention has as a still further object to provide a construction wherein the cards for display and moving at one rate of speed, and the independent card provided for attracting attention and moving at another and greater rate of speed, will be propelled from the same source of power.

F or convenience, Iliave illustrated the use of a spring motor in the form of clock works indicated as a. whole at 11 in Fig. 2 of the drawings, although it is to be understood that I do not wish to limit myself in'this regard as any other suitable typev of motive power'may be employed.

It'w1ll be seenupon reference to this figure and also upon reference to Fig. 9 that.

i the clock works 11 includes the spaced parallel frame sections 12, which are connected.

at opposite corners by suitable posts 13. Mounted for rotation upon the sections 12 is'a drive shaft 14- having its free extremity 15 squared to receive a key and operatively connected with and surrounding the said shaft isa suitable spring 16. Mounted upon the shaft 14 is a tooth wheel 17 which meshes with the pinion 18, carried by a shaft 19 operatively supported by the said frame sections.

Arranged upon one side of the shaft 19 and rotatably mounted upon the frame sections 12 is a driven shaft 20, which projects upwardly upon one side of the adjacent frame section 12. The shaft 20 is provided with a pinion 21 disposed to mesh with the tooth wheel 22 carried by the shaft 19 and is thus operatively connected therewith. Meshing with the tooth wheel 22 is a second pinion 23 which is mounted upon a shaft 24, the shaft 24 being also provided with a tooth wheel 25 disposed to mesh with the pinion 26 carried by the shaft 27, it being understood, of course, that the shafts 24: and 27 are operatively supported by the frame members 12. shaft 27 is a tooth wheel 28 which meshes with the pinion 29 carried by a governor shaft 30, the shaft30 being rotatably mounted upon the frame sections 12 and projecting to extend upwardly and laterally upon one side of the adjacent member to detachably receive at its free terminal, a governor 31. i

The clock works thus described may be detachably secured. to the base 10 in any Arranged upon the suitable manner, as by lugs 32 which are formed to receive suitable fastening devices, and inclosing the clock works and resting upon the base 10 is a casing 33. The motor thus presents a neat appearance, it, of course, being understood that the casing 33 may be ornamented in any desired manner to enhance the value of-the device for'advertising purposes, and it will be observed that the governor 31 is disposed exteriorly of the casing so as to be readily visible.

At this point, it should be stated that the ratio of gears between the drive shaftlet and the driven shaft 20 and between the said drive shaft and the governor shaft 30, is such that the governor shaft will rotate at a relatively higher rate ofspeed than the driven shaft, the shaft. 201 being moved rather slowly, while preferably, the governor shaft 30 .willturn at a relatively fast rate of speed. The reasons for so connectpear.

The governor 31 preferably includes a relatively straight flat plate whichis provided midway its ends, with a. socket 35 engaging the governor shaft 30. Arranged upon the plate 34: to extend upwardlythere from, is a card or other suitable device 36 which, for convenience in the further description of the invention, will be designated an attention device, the object of the card 36 being to arrest the attention .of a possible observer.

The card 36 upon one longitudinal edge thereof, is provided with a series of longitudinally spaced and transversely extending slits which define a plurality of tongues 37 which are alternately engaged with the plate 34: upon opposite sides thereof for detach-- ing feature, such for instance as being col? ored in ajpeculiar manner, but in the type ,85 ing the shafts 20 and 30 will presently apof attention device whichjI have shown in the drawing, the card36 is preferably pro-' vided with the word Look upon opposite sides thereof and arrangedin such position that a possible observei will readily .see the wordin passing the deviee,it being rememberedthat the governor31 will, whenthe device is in operation, be rotated. at a relatively highrate of'speed to further tend to arrest attention. i

Having thus described the motoir illustrated and the attention device connected.

therewith, I shall now proceed. to describethe means employed for operatively supporting the cards or other articles used for successive display.

Detachably secured at one end, to one side edge of the base to abut the adjacent face of the casing 33, is a vertically arranged post 38. The post 38 may be of any suitable material and may be connected with the base 10 in any desired manner as by screws 39. Upon the upper extremity of the post 38, is provided a laterally extending guide arm 40 which projects inwardly over the casing 33 and which is provided adjacent its outer extremity, with a suitable opening disposed in alinement with the drive shaft 20. The guide arm 40 may be formed of any suitable material such as sheet metal and is bent transversely adjacent one end to form a terminal lug 41 extending vertically of the post with the adjacent portion of the arm seating upon the upper extremity of the post. Preferably, the guide arm 40 is detachably connected with the post 38 and is held in position by a suitable fastening device 42 ex- 1 tending through the said. arm and into the adjacent end of the post.

Supported for rotation by the guide arm 40 and detachably connected therewith is a standard which, among other features of construction, includes a shaft 43 which passes loosely through the opening formed in the guide arm 40 in alinemcnt with the drive shaft 20. The confronting ends of the shafts 30 and 43 are squared as illus- Z trated in detail in Fig. 8 of the drawings to detachably receive a sleeve 44, operati'vely connecting the said shafts so that motion imparted to the drive shaft 20 will be communicatedto the shaft 43. In this connection, attention is called to the fact that in the provision of the connecting sleeve 44, the standard is detachably'mounted in position.

The standard previously referred to is further provided with a head indicated as a whole at 45 in Fig. 1 of the drawings. This head is secured to theupper extremity of the shaft 43 and provides a hub for operatively supporting a plurality of exhibit supporting arms or members, as shall be presently described.

More particularly, the head 45 includes an annular bearing member or disk 46, which may be formed of any suitable material and which is centrally apertured to loosely receive the adjacent extremity of the shaft 43, v

the said disk being supported, preferably by nut 47 screw threaded upon the shaft. Bearing over the member 46 in spaced substantially parallel relation thereto, is an annularretaining or guide member 48, the said member being in the form of a disk similar to the disk 46 and being centrally apertured to loosely receive the adjacent extremity of the shaft 43. interposed between the mem bers 46 and 48 and removably fitted upon the shaft 43, is a spacing member or washer 49 which supports the member 48.

Removably fitted upon the shaft 43 and resting at one extremity, upon the member 48 is a sleeve 49. Removably seating upon the opposite upper extremity of the sleeve 49 is an annular member or disk 50 similar to the disks 46 and 48, thedisk 50 having a central aperture formed therein to loosely receive the shaft 43. extremity of the shaft 43 is screw threaded to detachably receive a nut 51 and it will be observed that by properly adjusting the nut 51 upon the shaft 43, the several members 46, 48, and 50, may be rigidly clamped upon the shaft to turn therewith.

From the description just preceding, it will be seen that the head 45 is detachably connected with the shaft 43 and, as illus trated in the drawings, the members 46, 48, and 50, are concentrically mounted upon the shaft. Formed in the peripheral margin of the member 50 is a series of circumferentially spaced concentrically arranged openings and the member 48 is provided with a similarly arranged series of openings, the distance between adjacent openings in the member 48 being equal to the distance between adjacent openings in the disk 50.

The members 48 and 50 are arranged upon the shaft 43 with the openings therein in substantial alinement and oppositely disposed openings then provide pairs of coacting sockets disposed to operatively receive the exhibit supporting arms 52, one of said arms being shown in detail in Fig. 5 of the drawings. The arms 52 are each preferably formed from a length of suitable resilient wire, which is bent intermediate its length to provide a shank 53, from one terminal of which extendsat substantially right angles thereto a laterally disposed arm 54, the arm 54 adjacent its free extremity being reversely bent laterally. to provide a terminal shoulder 55 and having its free end thence returned to extend to a point in substantial alinemcnt with the arm 54.

The shank 53 of each of said. arms is removably fitted within coacting sockets formed in the head 45 and is supported at its free end by the member 46, the said.

shanks 53 being of such length as to extend through the guide member 48 to rest upon themember 46, as best illustrated in Figs. 1 and 2 of the drawings. The exhibit supporting arms 52 are thus detachably connected with the head 45 and are supported for rotative movement thereon by the shanks 53. i

Disposed for detachable connection with each of the arms 52 is a suitable card 56 in dicated in detail inFig. 4 of the drawings,

The adjacent upper able character and are of a transverse width to extend throughout the majorportionof the length of the arms 54, the said cards being each formed, adjacent one side edge thereof with a vertically arranged slot 57 which is arranged contiguous to one end of the card. Each of the cards 56 is also provided medially thereof with an opening 58. In connecting the cards 56 with the arms 51, the arms are passed through the slots 57 and the free terminals thereof are inserted through the openings 58, the shoulders 55 engaging within the said openings to maintain the cards in position as illustrated in Fig. 1 of the drawings.

Each of the cards 56 upon opposite sides of the longitudinally extending opening 57 formed therein is provided with longitudinally extending parallel folds or creases 59 to provide substantially, an intermediate offset portion 60 in which the slot 57'is arranged. The arms 5& are disposed to extend loosely through 'saidslots 57 and it will be observed that the cards 56 are thus mounted to pivot in a vertical plane upon the shoulders 55 of the said arms, this being for a reason which will be presently described. V

As shown in Fig. 1 of the drawings, the cards 56 are supported to depend from the arms 52 in radial relation to the head 45 and will, when the device is in operation, be r0 tated with the head through the medium of the clock works 11. Secured to the base 10 in spaced relation to the post 88 is a second post or upright 61 to the upper end of which is secured in any suitable manner a resilient finger or detent 62. Ihe finger 62 may be formed from a length of suitable resilient wire and is laterally curved adjacent its outer extremity as best shown in Figs. 2 and 3 of the drawings, to extend'into the path of the cards 56, the free terminal of'the said finger being disposed to engage the adjacent side margins 'of the cards 56 in substantial alinement with the arms 54, as shown in Fig. 1 ofthe drawings.

It will be noted that the finger 62 is ar ranged upon one side of and in advance of the vertical axis of the head 45 and is disposed to engage the outer edge of each of the cards 56 in a plane with the adjacent sideof the head to consequently arrest or restrain each of said cards relative to'the rotation of the head 55 in substantially the same plane. It will now be seen that as the head 45 then continues to rotate and the pivot point of each of said cards, or the" point where the shank of the arm carrying the card'engages the head, is moved away from the finger 62, the adjacent side edge of each of said cards will be caused to clear the free end of the finger to effect the release of the card; Preferably, the free extremity of the finger 62 is curved longitudi nally in the direction of rotation of; the cards 56 so that as the cards are thus moved by the head 15, they will slide freely upon the said finger to be released.

It will be recalled that the head 45' is preferably rotated at a relatively slow rate of speed so that as each of the cards 56' moves into position in engagement with the finger 62, the said cards will be detained in position for display, a corresponding length of time so that an observer will have ample opportunity to read any indicia appearing upon the cards, it, of course,-being understood that when the cards are thus each detained by the finger 62 which in turn, will serve to arrest the outer extremity of the arm carrying the card, the shank of said arm will rotate or pivot within the sockets of the head as thehead continues in its rotary movement.

Particular attention is now directed to.

the peculiar construction by which I effect the automatic reversal of each of the cards 56 upon their release by the linger '62, or in other words, the means by whicheach of the arms 52 is caused to swing through an arc of substantially 18 to pass through a ver-' shanks 53 of the exhibit supporting arms,

are disposed slightly upon one side of and out of vertical alinement with the openings formed in the member 50. 1 Consequently, the inner extremities of the said shanks are.

correspondingly moved to oneside to dis-* arms isdisposed in a-ver'tical plane upon one side of the other socket of each of said pairs. Consequently,when thearms'5 l are swung upon the head 4-5 to move through an arc of substantially 180, they will move in a plane tilted from the horizontal in a degree corresponding relatively to the inclination of the said shanks from the vertical.

It willflbe noted that the resilient finger 62 is arranged to so engage thecards 56 that the outer extremities of the arms 52 will be detained slightly in advance of and upon One side of the highest point in the plane in which the said arms travel so that when the head 45 rotates to a position to release eachof said cards, the arms will, by gravity, automatically pivot upon the head 45 to swing to the lowest point-of their movement in such plane. WVhen so released the arms will pass through a plane at substantially'right angles to the observer and accordingly present the reverse side of each card from that previously displayed under restraint of the finger 62, to view in substantially the same plane with thenext succeeding card then engaged by thesaid finger. This willbebest understood upon reference to Fig. 1 of the drawings, and I consider this a very important feature ofthe present invention, since the cards 56 are thereby, through the action of gravity, automatically reversed, while the means employed for effecting this result, is obviously exceedingly simple.

Since, as above stated, the members 18 and 50 are loosely mounted upon the shaft 43 and are clamped in rigid position thereon by the nut 51, it will be noted that the said members may be adjusted upon the shaft with relation to each other to simultaneously position the sockets formed in the member 48 from the vertical. relative to the sockets formed in the member 50 and accordingly adjust the inclination of the shanks 53. Since the arms 52 are caused to pivot by gravity upon the head a5, through the inclination of said shanks, it will be observed that in providing for the adjustment of the members 48 and 50, the arms may be ad justed to travel each in a plane tilted a greater or less degree from the horizontal. In this way, and as will be clear, a further adjustment is had of the rapidity with which the arms will pivotally swing upon the head d5 to reverse the position of the cards.

This adjustment by which the rapidity of the pivotal movement of the arms 52 is controlled is, as will beclear, a decided advantage, since where the arms 52 are caused to support relatively light articles such as cards as illustrated in the drawings, the member 48 may be adjusted to so incline the shanks 53 that the said arms when released will quickly swing upon the head 45 so that with undue force. In such instance, the

member 4:8 may be adjusted accordingly, so that the arms will each travel through their arcuate path at the desired speed.

Since the arms when pivoting upon the head 45 in the manner heretofore described, move each in a plane tilted with respect to the head or with respect to the horizontal, attention is directed to the construction whereby the cards 56 are disposed to maintain their proper position with relation to the horizontal at the time of display, both when restrained by the finger 62 and when swung to the opposite side of the head in1- mediately after their release by the said finger. It will be noted upon particular reference to Figs. 1 and 3 of the drawings, that as the head 45 is rotated, the card 56 engaged by the finger 62 will be restrained to move the arm carrying the said card pivotally upon the head l5 against its normal tendency to gravitate to substantially the highest point of movement oil said arm in In order to.

the plane in which it travels. maintain its proper position with relation to the vertical, the card 56 carried by the said arm and engaged by the finger 62 must, therefore, pivot in a vertical planeas the arm carrying the said card moves from its lowest point of movement toward its highest point of movement, and until it is released by the said finger. The presence of the shoulders 55 upon the arms and pivotally receiving the cards and the provision of the vertically arranged slots 57 will now be apparent. As each of the cards 56 is re strained by the finger 62, the cards will, through the action of gravity tending to move them to normally assume the vertical, pivot. upon the shoulders 55 to consequently maintain their proper position, the intermediate portions of the arm 52 moving within the slots 57 as the cards are thus pivoted. It, of course, follows that when the arms are released to reverse the cards, the cards will pivot upontheir arms to consequently assame a horizontal position when so reversed.

From the preceding description, it will be seen that in the construction which 1 pro:

vide, the action of gravity is employed both for shifting the cards to effect the reversal thereof and for automatically maintaining the cards in proper normal position with re lation to the vertical at the time of display. Obviously, this is an advantageous arrange ment, since the necessity of providing mechanical means for effecting the same results, which means heretofore have been expensive and cumbersome, is obviated. Furthermore, it is to be observed that the cards are positively connected with the arms to move therewith while owing to the presence of the slots 57 adjacent the inner margins of the said cards, the possibility of one card interfering with'adjacent cards will be eliminated.

Normally, the arms 52 rest at the lowest point of their movement in the plane in which they travel as shown in Fig. 1 of the drawings, and as the head 45 rotates to successively bring the cards 56 into engagement with thelinger 62, the cards in the rear of the card engaged by the said finger, upon being brought under the restraining influenceof the finger, engage each other and, as the head then continues to rotate, are swung upon the head to the highest point of their movement in said plane. Consequently, as each card is so moved and is brought into direct contact with the finger to be released thereby, it will swingingly gravitate upon the head to reverse its position as previously described. By this construction, it will be observed that the. action of my improved.

device is entirely automatic and that under the influence of the clock works 11, the cards 56 will be continuously exhibited.

In this connection, it is desiredto bring attention to the attention device 36 and its rai er rotary movement with relation to that of the cards 56. Since, such of the cards 56 presented for display will, for the greater portion of the time be held stationary so far as their pivotal movement upon the head 45 is concerned, the advantage of employing the attention device, the movement of which is continuous and at a rate ofspeed relatively much faster than the rotary movement of the head 45, will be clear. For instance, the attention of a person passing the device at a time when the cards presented for display were in the position shown in Fig. l of the drawings and were, relatively speaking, stationary, might not be attracted to the said cards but it will be seen that notwithstanding this fact, the attention device bearing the word Look would, under ordinary circumstances, arrest the attention of the observer who would then naturally peruse the cards displayed. I, therefore, regard the provision of the attention device asavery important feature of the present invention as well as the feature of arranging said device to rotate continuou'sly at a relative speed greater than the rotary movement of the cards 56.

In Fig. 9 of the drawings, I have illustrated a slight modification of the invention wherein the arms 52 are caused to pivotally gravitate upon the head 45 by inclining the shaft 43 with relation to the verticahthe post 38 and the guide arm 40 in such instance, being arranged upon one side of and out of alinement with the drive shaft 20.

positioned with relationto each other that the openings formed in said members will to the axis of the said shaft.

Otherwise, the construction disclosed in this modification is similar to that found in the preferred form of the invention and a further detailed description, Wlll, therefore, not be glven.
